Possessives of proper names ending in S
What is the possessive of Jesus?
Different style guides differ about whether to use an apostrophe S after a proper name ending in S, such as James or Jesus.
Some recommend adding an apostrophe S for some "common" proper names (Charles's), but not Biblical names (Jesus'). Some say that all names should take an apostrophe S (Jesus's), while others says that names ending in S should only take an apostrophe. Still others take into account how many sibilant (S) sounds the word has when determining whether to add an S after the apostrophe. Many guidelines reflect the way the word is often pronounced (Jesus' = Jee-zus, not Jee-zus-iz). Check with your preferred style guide to see its recommendation.
